REGULATOR FOR GAS-BURNERS.

Specification of Letters Patent No.

To all 'whom t may concern:

Be it known that I, ANDREW MAYER, of the city and county of Philadelphia and State of Pennsylvania, have invented a new and Improved Regulator for GrasBurners; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, forming part of this specification, in which- Figure 1, is a section, full size, taken through the center of a gas burner, having my improved regulator applied. Fig. 2, is a section, on an enlarged scale, of the regu lator detached from the burner. Fig. 3, is a perspective view of the valve.

Similar letters of reference indicate corresponding parts in the several figures.

This invention consists in making the regulating valve in the form of a hollow cone, which is perforated at the apex, to allow of the passage of no more gas than is suicient lto supply the burner when the gas is at the highest pressure, and has lifted the valve to its seat, at the top of the box which contains it, and whichhas openings round its base or lower edge, which openings when the gas is at its lowest working pressure and the valve rests upon the bottom of its box, will allow sufficient to pass, to supply the burner. A single valve of this description works more effectively than a number of disk valves, such as are now in use, applied one above the other, and does not produce the disagreeable whistling noise produced by the disk valves.

To enable those skilled in the art, to make and use my invention, I will proceed to describe its construction and operation.

A, is the gas burner, and, B, is a chamber below the burner, containing the valve box, which is composed of a short tube (a) and two inverted cups (Z2, c) forming respectively the top and bottom, the top (c) being perforated to form a seat for the valve, C, and the bottom having an opening (f) for the passage of the gas. The conical valve, C, may be made of brass or other metal, very thin, so that it may be light enough to be lifted by the gas when at a high pressure.

11,674, dated September 12, 1854.

The perforation (ci) at the apex of the cone, is only just large enough to allow of the passage through it of so much gas, as it is desired to burn, at the highest pressure. The openings (e, e) round the base, are merely notches in the bottom or base of the cone, and the sum of their areas should be sufficient to allow of the passage through them of as much gas, as is necessary at the lowest pressure. The valve `is so arranged in the box, that is to say, that the box is of such a depth, that when the opening of the valve or space, between it and its seat, is suiicient to allow the passage of the proper quantity of gas, at the lowest pressure, the valve rests upon the bottom of the box.

The operation of the valve is as follows: The pressure above and below, so balances and supports the valve, that the opening between the valve and its seat is always proportioned to the pressure of the gas, the valve falling and the opening being enlarged, as the pressure in the pipe diminishes, and the valve rising and the opening being contracted as the pressure increases. As soon as the pressure of gas becomes excessive, the valve is lifted to its seat, and closed, but the gas is not shut oli', as a s'uicient quantity will pass the perforation which is only necessary to prevent the shutting oli1 the gas, by any sudden increase of pressure.

Having thus fully described my invention,

I will proceed to state what I claim anddesire to secure by Letters Patent.

I do not claim the employment of a conical valve to regulate the ow of gas, irrespective of the peculiar construction of the said valve, but

The employment, as herein described, of a hollow, conical valve, perforated at its apex, and having openings around its base, and being arranged with a box which receives the gas, through an opening under the valve, substantially as herein set forth.
